Based on above-mentioned scheme, combine concrete use, can see out from elevator structure operation principle, when normal operating, overspeed governor wire rope is by overspeed device tensioner's effect, and it moves with elevator car synchronous operation, and the overspeed governor pitch circle is with the car with fast. Even under the braking working condition of a traction machine, the rotational inertia of the speed governor is very small, so that the synchronous operation with the elevator car can be still kept, and the pitch circle of the speed governor is in the same speed relationship with the elevator car.
Therefore, the initial speed of the elevator car when the elevator car starts to brake can be measured in real time by utilizing the Hall sensor in the prior art. Since we also know the end velocity v of the stop endingt，vtAnd = 0. If the time t required for stopping the elevator car can be measured again, an average deceleration strip ã, ã = (v)t- v0)/t= - v0/t；
This scheme utilization hall sensor surveys elevator car system and stops initial velocity vtRecording the moment of starting braking; and measuring the time t required by the braking of the elevator car by using a level signal output by an elevator stopping state recognition device arranged at the speed limiter.
The test switch of the device can trigger the braking of the elevator through the contact point of the speed limiter switch; hall sensor tests the speed simultaneously and passes to the tester, and this patent tester power can be got from elevator switch board.
